Most tech-education products in the 2010s and 2020s fell into one of two camps: bootcamps that taught people to code quickly enough to get a first job, or massive open online courses that let anyone watch pre-recorded lectures at their own pace. Bradfield School of Computer Science occupied a different niche entirely. Its students were typically already working software engineers - often self-taught or bootcamp graduates - who had learned to build things but had never formally studied the computer science underneath their day-to-day work: how algorithms are analyzed, how computers and networks actually function, how databases are built, how distributed systems fail.
Bradfield's answer was a curriculum built around textbooks, primary research papers, and small-group programming exercises, taught by instructors with real depth in narrow subjects rather than generalist course creators. Classes were intentionally kept small so that discussion and problem-solving stayed central, in contrast to the passive-viewing model of most online courses. This approach won the school a loyal following and strong word-of-mouth reputation among engineers in the Bay Area and beyond, even though it never tried to scale to the size of a mass-market bootcamp or MOOC platform.
Over its roughly eight years of operation, Bradfield offered two main formats. Standalone courses covered a specific, deep topic over a shorter period - examples include Computer Architecture, Deep Learning for Engineers (taught by Dr. Brian Spiering), and an Engineering Leadership course taught by Xavier Shay - and were aimed at engineers who wanted to fill a specific gap in their knowledge without committing to a long program.
The flagship offering was a 12-month, part-time, live-online curriculum built for mid-career engineers who wanted a structured path through core computer science over the course of a year, without leaving their jobs. Students could historically attend classes in person in San Francisco or participate live online, and across its run the school reports having taught more than 1,000 students in total.
In 2023, founder Oz Nova put Bradfield's live cohort courses on indefinite hiatus once the final active cohorts had graduated. By his own account, the decision wasn't a response to the school struggling - curriculum quality and brand recognition had both grown steadily - but a personal choice about where to direct his time and energy going forward, given that running a live, instructor-driven school at that level of quality is inherently time- and attention-intensive.
In place of new live cohorts, Nova has focused on CS Primer, a self-paced platform intended to carry forward the philosophy and much of the content of Bradfield's courses in a more affordable, asynchronous format that can reach a wider audience than a live, San Francisco-centered school ever could. As of this writing, Bradfield's own site functions mainly as an archive and point of contact rather than an active enrollment page, and prospective students interested in Bradfield's teaching approach are directed to CS Primer instead.
Bradfield's live cohort courses have been on indefinite hiatus since 2023; the school is not currently enrolling new students in live classes.
Bradfield taught foundational computer science topics - algorithms and data structures, computer architecture, networking, operating systems, databases, and distributed systems - aimed at practicing software engineers.
Bradfield was founded and run by instructor Oz Nova, who taught at the school for about eight years before pausing live cohorts in 2023.
Not as a live Bradfield cohort. Founder Oz Nova has redirected the curriculum and teaching philosophy into CS Primer, a self-paced platform.
CS Primer is Oz Nova's self-paced platform intended to carry forward Bradfield's curriculum and teaching approach in a more affordable, asynchronous format.
No. Bradfield focused on computer science fundamentals for engineers who already knew how to code, rather than teaching people to code for a first job.
Bradfield was based in San Francisco, California, and historically offered both in-person and live-online instruction.
The school ran live cohorts for roughly eight years before founder Oz Nova put new enrollment on indefinite hiatus in 2023; the flagship program itself ran 12 months part time.
